I was using 2 lenses on the spirit bear site: 70-200mm f/2.8L IS II and the 200-400mm f/4L IS+1.4x
Sometimes I was at 200mm, sometimes using the 200-400mm at 400mm with the internal 1.4X on. Sometimes I was using an external 1.4x extender.(784mm)
The shot with the fish was taken at 200mm ISO 1600. It is dark in the wood and I shot regularly at ISOs between 3,000 and 6,000 ISO and a few times at ISO 10,000 (some are included in the video you can see using the link in the post.)
The shot with the Grizzly scratching neck is with the 70-200mm on a 1D IV + a 1.4 (280mm). The swimming Grizzly with the 300mm f/2.8L IS on a 1D IV.
I was using mostly the 1DX in the forest. I also used the 5D III as a backup and second camera (you don't change lenses when it's raining and there, it's pouring...)
Hope this help,
PS. I as close to the spirit bear: 30 to 40 feet. It was quite a trill. We had great guides (native tribe). The nearest I got from a spirit was 5 or 6 feet (I was like a statue. There was no real problem because the food market was open=salmon river
right next to us)
